1 . The COVID-19 lockdown worried me. I worried about what the weeks and months ahead might look like. I decided to take the idea of “love the neighbour” seriously.
On a Saturday morning, I made a sign that said, “Have a nice day,” and stuck it on my kitchen window, with a smile face. A while later that day, the neighbour living across from me, taped up a sign on the window with a message for us. “Thank you. You too!” We went on like this for a few days, back and forth, like an echo, and I thought of how this would be a nice story for us all：move from strangers in the beginning to good friends in the end.
Somewhere around Day 5, I positioned “Beaker the Muppet” in the window, and they responded with a cute stuffed dog. Then I put a note of a Mary Oliver poem about spring to raise the bar. Maybe I was showing off. Sure enough, no “echo” this time.
The next day, Dewey was barking at their dog in the backyard. I saw one of the guys when I went out to stop my dog. “Sorry, we didn’t find a poem,” he said. “We meant to,” he added. “And then we never did.” “That’s okay,” I replied. And we both went back inside.
During the following days, I also ran into the neighbour in the driveway some times as we walked our dogs, and found the note already started to feel a little silly. What if my notes were a chore to them, and not a charm?
For months, I had avoided my favorite blocks sidewalk that cut through my neighbourhood. Going for walks these days made me sad, or mad, because the story had no good ending.
I kept thinking, “How do I love you, my neighbour, like I’m supposed to? I have decided after this is all over, I will finally have all my neighbours over for dinner.”
Maybe we can have a little laugh together about how we tried to be kind. We’ll say even during the hard time, nothing can lock us.

3 . City: Hangzhou
Launched: 2008
Size: 2,965 stations/ 69,750 bikes
Price: $28.59 deposit(押金) + time charge
While taking a look at this city, you may see the best bike sharing in the world. As the second on the planet by size, the Hangzhou Public Bicycle System is one of the most common and useful shares, largely because it’s combined with public transportation: a single card can be used in subway, bus, taxi and bike sharing. Residents and tourists can put down a deposit of 200 Chinese Yuan (about $29) and ride for an hour for free in this scenic city. Each additional hour costs only $0.15. It was also the first new-generation bike-sharing system in China.
City: Barcelona
Launched: 2007
Size: 420 stations/6,000 bikes
Price: $61.93 per year
Barcelona’s Bicycling Program developed Spain’s bike-sharing business in a big way. This program took off like wildfire on wheels, and because four times bigger in one year. It inspired different copycat programs all over the country. Today, Spain has 132 bike-sharing systems. The program is one of the world’s most respected and popular shares. But it is only open to residents and tourists are not allowed to use them.
City: Paris
Launched: 2007
Size: l,751 stations/23,900 bikes
Price: $38. 52 per year/ $2.26 per day
Bike sharing in Paris is the star of the world. Launched in 2007, it is the world’s largest outside of China. Cheap by American standards, you can ride around Paris on a $1.7 day pass—the first half hour of each trip is free. Because this system covers the city with an average of 50 stations per square mile, it’s a favourite with both locals and tourists.

4 . In 1840, the French painter Paul Delaroche saw the first daguerreotype — an early photographic process — and declared that “from today, painting is dead”. One can understand him feeling threatened by the technology, but we know now he was dead wrong: instead, that year marked the birth of the art of photography.
Throughout history, there’s been fierce debate about the boundary between science and the arts. It continues in the form of the great AI debate. In February this year, the winning photo in an Australian photography competition was created entirely by artificial intelligence; and months earlier, a man used text-to-image software to take out the top prize in the Colorado Art Fair. The software can use billions of online images, identified by digital labelling from innovations like alt text. But the question remains: do AI art generators copy or steal other artists’ work?
“Unlike copying/stealing, there’s also taking inspiration,” artist Koach argues. “This accumulation (积累) of seeing and remembering art from other artists will, at one point, become apparent and trigger inspiration. Isn’t this the machine’s way of ‘taking inspiration’?”
The artistic community seems split. Some celebrate the removal of barriers into the art industry; anyone can be an artist these days. Others are joining class actionis, accusing the tech companies of stealing art without credit, consent or compensation.
As a journalist, I’m fascinated but horrified by the development. Apps like Stable Diffusion, Dall-E and Midjourney can imagine a deserted island in the style of Monet. But if you ask for images of a CEO, it’s generally an older white male. Nurses? Almost all female. While humans are biased (有偏见的), technology is copying the unfairness at scale.
By contrary, Koach is keen to reframe AI art as simply another design tool. “The artist and the technology are intertwined throughout the creative process,” he says. He looks for a hopeful future: “AI art might shift our values away from, ‘Does this image have all the colours, compositions and styles that I want to?” ‘Is this image meaningful or special in some other way?’.”
But if we want to live with this technology, we need to be proactive. Learn about the complexity and bias within AI and keep a close eye on where it’s going. Regulate the industry to protect users and creators. And outsmart the algorithms (算法).

5 . Beethoven wrote many famous pieces of music, but he’s probably best known for his nine symphonies. A symphony is a long, complicated piece of classical music, usually divided into four parts. The four parts are often linked by “themes” — repeated musical ideas that tie the whole piece together.
When Beethoven died in 1827, he had some ideas for a 10th Symphony. But all that he left behind were some notes about the piece and a few “sketches” — short bits of written music.
In 2019, a special team of musicians, computer scientists, and historians was formed. Their goal: to try to complete Beethoven’s 10th Symphony to celebrate his 250th birthday. The team didn’t just want to complete the symphony, they wanted to come as close as possible to producing the symphony that Beethoven meant to write. That’s where deep learning came in. Deep learning — sometimes called Artificial Intelligence (AI) — describes computer programs that sort deeply through huge amounts of information. This allows them to find patterns humans may not have noticed. The programs can then use those patterns in new and surprising ways.
To train an AI to help with the symphony, the team turned every piece of music that Beethoven ever wrote into a form the computer could understand.
By feeding the program all of Beethoven’s music, the AI could look for patterns in the way Beethoven wrote. This included, for example, how he re-used simple melodies all through a piece to create a theme, or how he moved between different parts of the symphony.
Other members of the team studied Beethoven’s notes and sketches, and worked to figure out what Beethoven was planning to do. Where in the symphony did he plan to use each little bit of music that he left?
________. They played a few minutes of music created by the AI for Beethoven experts, musicians, and reporters. No one could tell which parts had been written by Beethoven and which parts the AI made up.
Finally, the AI had the challenge of trying to connect the little musical bits into a symphony. It took over two years, but the team was able to complete Beethoven’s 10th Symphony. Not simply a melody, but 40 minutes of music for a full orchestra — a large group of musicians playing everything from string instruments, like violins, to trumpets, flutes, drums, and piano. So Beethoven now has a 10th Symphony. And though Beethoven didn’t write it all, the team feels sure that the music is very much like what he might have written, if he’d had the chance.
